Taking the relationship between new urbanization and urban ecological security protection as research object,based on pressure- status- response model,taking Gaochun( Gucheng Lake basin) and Zhangjiakou( Guanting Reservoir basin) as the examples,basin ecological security in its new urbanization process was evaluated. Based on the principle of comprehensiveness,representativeness and data availability,evaluation indexes were selected,and index system was established. Mathematical function of evaluation indexes was established,and security index of each evaluation indicator in index layer was determined. Using weighted average method,ecological security indexes in the two areas were obtained. On the basis of comparison and analysis,it is proposed that we must deal with urban ecological security problem in new urbanization process,thereby truly achieving ultimate value orientation of new urbanization construction oriented by people.
